1. S³DOC as a durable medium in Bank

If you are covered by MiFID and PSD, you know the problem of a durable medium. S³DOC responds to the problem of providing consumers with essential terms and conditions on a durable medium. A durable medium is a medium that technologically blocks the possibility of modification and removal of documents. The Blockchain platform used in S³DOC and additional cryptographic mechanisms allowed to achieve compliance with the definition of a durable medium.

S³DOC features for durable medium:

allows you to add a document to the system
generates a unique document key
allows access to the document only through a unique key (no possibility to list the contents of the register with documents)
guarantees that the document cannot be modified
guarantees that the document cannot be deleted
provides lifelong access to the document
access to read documents is not restricted in any way (if you know the unique code of the document, you can read it)

How to use the system?

Let’s assume we have a bank and a client for that bank. The Bank must provide the customer with the regulations for using the bank account on a durable medium.

The Bank prepares a document with the Regulations
The Bank enters the document with the Regulations into the S³DOC system.
The S³DOC system generates a unique document access key (the key may be available as a unique url link).
The Bank verifies whether a relevant document is held under key.
The Bank sends to the customer (or many customers) by e-mail an url link leading to a document with Terms and Conditions.
The customer receives an email with a unique url link to the document with the Terms and Conditions.
The client clicks on the unique url link and downloads the document. This operation may also be performed after the term of the agreement with the Bank.

2. S³DOC as a durable medium in e-commerce

The Act on Consumer Rights imposes an obligation on entrepreneurs to use a durable medium. The S³DOC system is an answer to the problem of providing consumers with, among others, regulations of Internet services and essential conditions of the contract on a durable medium. The term durable medium is understood as a medium which in a technological way blocks the possibility of modification and removal of documents. The components and cryptographic mechanisms used in S³DOC allowed to achieve the state of compliance with the definition of a durable medium.

S³DOC system features to ensure the status of the durable media

allows a document to be added to the system
generates a unique document key
allows access to the document only through a unique key (no possibility to list the contents of the register with documents)
guarantees that the document cannot be modified
guarantees that the document cannot be deleted
allows lifelong access to the document
access to read documents is in no way restricted by permissions (if you know the unique document code, you can read it)

How to use the system?

Let us assume that we have an Internet Portal and a Client of this Portal. The Portal must provide the Client with the rules of providing services on a durable medium.

The Portal prepares a document with the Regulations
The portal introduces the document with the Regulations into the S³DOC system
The S³DOC system generates a unique document access key (the key may be available as a unique url link)
The portal verifies that the relevant document is under key
In the process of acceptance of the Regulations, the Portal places an url link leading to a document on a durable medium containing the Regulations of providing services
The client has the possibility to “click” and open the document. Durable carrier guarantees the customer invariability of the regulations. The customer can download the document to a local disk.
The portal, by means of e-mail or SMS, sends the client (or many clients) the url link leading to the document with the Regulations.
The client receives an email or SMS message with a unique url link to the document with the Terms and Conditions.
The client “clicks” on a unique url link in an email or SMS and downloads the document. This operation can also be performed after closing the account on the Web Portal

3. S³DOC eSign – digital signature

The legal basis for such IT solutions is the EU regulation – eIDAS.

eIDAS is a 2014 EU Regulation. It regulates, among others, issues related to the digital signature in relation to electronic transactions. The regulation defines 3 types of digital signatures: “ordinary’, advanced and qualified. The former is already sufficient to make declarations of intent.

Definition of an ordinary digital signature: „Digital signature’ means data in digital form which are attached to or logically associated with other data in digital form and which are used by the signatory as a signature;

This means that, according to the eIDAS Regulation, an digital signature is a means of establishing that certain data in electronic form have been attached to or are logically linked to other data in order to be signed by an individual.

Polish law also provides for making declarations of will in digital form.

How to use the system?

Suppose we have a loan company and its client. The loan company must provide the client with a loan agreement on a durable medium and receive the client’s acceptance of the agreement.

The loan company prepares a document with the Agreement
The loan company enters the contract document into the S³DOC durable medium
The S³DOC system secures the document and generates a unique document access key (the key may be available as a unique url link)
The loan company is preparing a document for acceptance in the S³DOC eSign module
The S³DOC system generates a unique link for document acceptance
The loan company sends an SMS to the client a link to accept the document
The client receives a link and opens it
The client sees the content of the document and the possibility of making a decision (acceptance or rejection of the document)
After accepting the document, the client receives an authorization code from the S³DOC eSign module
The customer enters the authorization code confirming his decision (he submits a declaration of will confirmed by a single authorization code)
Durable carrier guarantees the customer invariability of the Agreement. The customer may download the document to a local disk.
In the history of the document, the lending company sees what decision the client has made (full digital signature metric is available)

4. S³DOC as protection against early opening of tenders

Each action has several important dates in the cycle. These include, inter alia, the deadline for the submission of tenders and the deadline for the opening of tenders. The first term is easy to verify. The easiest way to do this is to temporarily switch off the bidding function after the specified deadline.

It is worse to protect against the opening of bids before the deadline set in the tender expires. Earlier access to offers makes it possible to manipulate the results of tender procedures. Despite the many different security measures in standard solutions, there is always an administrator who has access to everything in the system, including complex offers.

The S³DOC system solves the problem of unauthorized early opening of tenders.

S³DOC features for secure offers

allows you to add a document to the system
documents are divided into blocks and saved in a way that makes it impossible for the administrator to view them (only the system knows the algorithm of combining blocks into a whole)
access to documents may be limited in time (documents accessible only after the specified time limit)
generates a unique document key
allows access to the document only through a unique key (no possibility to list the contents of the register with documents)
guarantees that the document cannot be modified
guarantees that the document cannot be deleted
provides lifelong access to the document

How to use the system?

Suppose we have a Purchaser and a Supplier making an offer. The definition of a tender procedure stipulates that a tender is submitted in S³DOC and that the procedure is accompanied by unique document codes received from S³DOC.

The Purchaser shall launch the procurement procedure
Supplier adds the offer document to the S³DOC system by setting the opening date of the offer
The S³DOC system generates a unique document access key (the key may be available as a unique url link).
The Supplier shall provide the Purchaser the document codes from the S³DOC system.
The S³DOC system blocks access to documents until the deadline for opening offers is reached.
After the deadline for opening the offers has expired, the Purchaser shall collect the documents using the document codes received from the Supplier.

5. Archive of diplomas, certificates, and printed materials

6. Archive of certificates of vaccinations or tests performed for COVID

The S³DOC system, thanks to its built-in cryptographic mechanisms and the use of Blockchain technology, allows documents to be stored in an undeniable way. This means that the content of the document cannot be modified once the document is stored in the archive. Additionally, time stamp information is recorded in an undeniable way, which determines the exact date when the document was added to the archive.

7. Medical Records Archive

The S³DOC system secures stored documents or test results preventing modification at any time in the future. Yes
